I have looked over and tried many of the proposed solutions to this problem at asp.net, but nothing seems to work for me.
Perhaps my situation is a little different.
Within UpdatePanel I have a GridView. Within this gridview, there is a DropDownList and Image. DropDownList is loaded by code behind. Image.ImageUrl is set to DropDownList.SelectedValue. This works ONCE. After that, when user selects a different value from DropDownList (which is set to AutoPostBack), Image.ImageUrl is set to DropDownList.SelectedValue.
But instead, I get the dreaded "message received from the server..."
BTW, no Response.Write() in my code. Also, take away UpdatePanel, and all works as needed, except for the "bumpiness" of page load.
Help would be most appreciated.
